Help with Arrays!

[TheAtomic]

Basically I have two 'sets' of rollover images on a a page. The first example is on everypage, but the second changes depending on what page you are on.

When I had just the one set the rollover worked fine, but now I introduced the second set, the rollovers are just referring to the second example below.

I guess its a problem with addressing the array and the second array is overwriting the first?

Any Ideas?

var menus = new Array('home','env','admim', 'research', 'business', 'services', 'people', 'intranet', 'vacancies', 'contactus');

var i;
var imgs = new Array(menus.length);
for (i = 0; i < menus.length; i++) {
imgs[i] = new Image();
imgs[i].src = 'buttons/topmenu_' + menus[i] + '_mo.gif';
}

function mm(obj, i) {
obj.ori = obj.src;
obj.src = imgs[i].src;
}

function mm2(obj) {
obj.src = obj.ori;
}

var menuspeople = new Array('a2z', 'faculty', 'resstaff', 'postgrad', 'adminstaff', 'technicians');

var i;
var imgs = new Array(menuspeople.length);
for (i = 0; i < menuspeople.length; i++) {
imgs[i] = new Image();
imgs[i].src = '/env/_henry/buttons/people_' + menuspeople[i] + '_mo.gif';
}

function mmpeople(obj, i) {
obj.ori = obj.src;
obj.src = imgs[i].src;
}

function mmpeople2(obj) {
obj.src = obj.ori;
}

Yes - the problem is that you're overwriting your "imgs" array with the second lot of data.

One (of many) ways around this would be simply to rename the "imgs" array for the second lot of code.

Hope this helps,

Yes, your imgs array is being overwritten. You can rename one of the arrays, or use:

function mm(obj, i) {
obj.ori = obj.src;
obj.src = 'buttons/topmenu_' + menus + '_mo.gif';
}

for your primary rollover code, and:

function mmpeople(obj, i)
{
obj.ori = obj.src;
obj.src = '/env/_henry/buttons/people_' + menuspeople + '_mo.gif';
}

for your secondary rollover code.

Cant believe I missed the imgs Array!

Doh!

If you use the function modifications that I wrote, it doesn't matter if you overwrite the imgs array.
